Not sure what you mean with Data Services, but there are so many products in the Data Platform sphere, I can't keep track of them all.
In plain SQL query you can do:
SELECT BIL, POSKOD, STATUS, KETERANGAN, LOKASI,
row_number() OVER(ORDER BY BIL) / % 8 + 1
FROM tbl
The row_number function numbers the rows ordered by what you specify in the ORDER BY clause. % is the modulus operator.
